Actually the long runners were the key to the economical Slant6. Compared to other straight sixes in the sixties, the AMC, Chevy, Ford, all of which ranged from 17-19MPG, the slant 6 I owned in 1969 got a consistent 21MPG, with an automatic. My Dad's '74 with three on the column (and 225 Cu In.) regularly got 24MPG - both pulling cars in the 3400 pound range (Valiant). In 1961, my Dad bought a brand new Plymouth station wagon with the 225Cu In slant 6 and 3 on the tree, it also constantly got 21MPG, pulling one of the largest wagons in history. And finally, in 1976, Plymouth came out with a car they called the "feather" Duster, a 2door slant back Valiant, equipped with the same slant 6, 4 speed OD tranny, achieved 27-28MPG. Add to excellent gas economy, the engine's renowned durability, and you have a winning combination.

If any vehicle will benifit from this , I think the vanagon will. The fuel is injected almost directly into the cylinder and gets almost no time to vaporizeor mix with air before it is burned. An engine on the opposite end of this spectrumn is the old chrysler slant six. The intake manifold had a couple of runners that were almost 2 feet long.The fuel had more time to vaporize and mix with air. It still got lousy gas mileage. |
